Trickster's Intuition

You're one sly person, and skilled at the art of trickery. You gain proficiency in the deception skill, and have advantage on checks made to see through other’s lies, or to check if they are lying. You can also imitate the behavior, writing style, or vocal sounds and patterns of a creature if you spend 24 hours studying that specific behavior or pattern, allowing you to roll with advantage and double your proficiency bonus when making checks using that specific behavior or pattern.
